Tenacity does not list that it can be tank mixed with fertilizers and does not list fungicides such as Propiconazole 14.3 either, only other post emergent herbicides. While they may not be an issue as long as you are following each products labels for rates and the most restrictive we would generally recommend only using 1-2 products at a time and doing a test on a small basis for compatibility, saftey and efficacy before treating large areas.
